IMPROVEMENT IN BED-BOTTOMS.

Specification forming part of Letters Patent No. 118,834, dated September 12, 1871.

To all whom it may concern:

Be it known that I, PETER AGGER, of Gincinnati, in the county of Hamilton and State of Ohio, have invented a new and Improved Bed- Bottom; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing making a part of this specification, in which Figure 1 is a perspective, Fig. 2 is a transverse section, and Fig. 3 a sectional view of the spring.

Similar letters of reference indicate like parts.

My invention relates to that class of bed-sprin gs which is placed underneath the bed-slats; and it consists in the peculiar form of the spring, whereby great elasticity is secured and the spring prevented from slipping upon the slat as the latter moves up and down, and the attachment of the spring to the bedstead is by a simple gimlethole and Without extra fast-enin gs.

In construction my invention is substantially as follows: A A are the bed-posts5 B B, the side rails; b b, cleats nailed or glued on rails B B, into which the springs O are fastened. The construction of the spring is more plainly seen in Fig. 3. It is composed of a single wire, bent at its center so as to form a seat, a, in which the slat will rest. The wires on either side of the seat 6 are then outward and parallel with each other and formed in coils g, and thence back toward seat 0 and formed in coils h, which are in the same vertical plane with seat 6, though separated from each other, so that said seat and slat may sink between them. From the coils h the ends i of the spring-wire are bent directly downward so as to enter plain gimlet-holes in the rails b, all of which is clearly shown in Figs. 2 and 3. From the above description it will appear that the spring is so constructed and arranged that when pressure is applied on the slat D it will have no friction on the spring, as the are through which the part 9 of the spring passes is counterbalanced by the movements of seat 6, thus equalizing the horizontal motion of the spring where it comes in contact with the slat. At E are seen small wire hooks, which keep the spring 0 engaged with the slat D.

The operation of my invention becomes obvious from the foregoing description. When it is desired to take the bedstead apart the slats are removed by slightly turning the hooks E, thus releasing the slat D, after which the rails B are easily removed, as in the ordinary bedstead.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A compound spring, constructed with coils g and h, and seat 6 in same vertical plane with coil h, and operating as and for the purpose herein specified.
